fixing an avi file

[bagatur]

i have this movie which is somehow corrputed - at some point the
image becomes unclear for several seconds, then everything
is back to normal, BUT when i convert it to svcd - after this point the sound
is out of sync with video( although while playing the avi i didnt have
any problem).
is there anyway to fix this? or i just have to get another version of this movie?

you can either fix it or try and get another copy. to try and fix it: load the file in virtual dub>video>scan video stream for errors. when its done >audio>direct stream copy then video>direct stream copy then file>save as avi. this should fix the file. hope that helps ya

hey, tenders.
it kinda helped in a sense that it removed all unreadable frames
(replaced them with the very last frame before the series of
unreadable ones),
but the problem was that after that the audio is still out of sync with
the video - that didnt change .
any ideas how i could fix it?

You first have to define what you mean by out of synch. Is the audio out of synch throughout the whole movie, or is it okay at the beginning, then gradually goes more and more out of synch?

it's quite weird with this file...
if i watch the avi on my computer - then the sound is ok thruout the
movie, but when i encode it to svcd with tmpgenc, then the sound is
ok up to 2/3 of the movie, and there is this corrupted part of the movie
where video is really messed up for like 10 seconds, so after this part
the video is delayed by like 3-5 seconds( again, if i watch the avi,
the sound is ok even after this part).

is the video corrupt on the avi version when you watch it at that same point but the sound stays in sync on the avi? if that happens on the avi too. all you need to do is remove the audio from the the avi. with virtiual dub. this is somthing you should do anyway for svcd. becasue the sound is compressed on the avi and u need to make it a wav., so remove the sound from the avi and when you use the tmpegnc place the video and the audio seprate then create. this should be ok.

correction use dvd2avi to remove the compressed audio to wav.
